STEPHEN J. van' infami, or' cEDARnaPi-Ds, IOWA,v nssrerironcro zr. G.omimvsr COMPANY, or CEDAR Raisins, Iowa, a OOItPOnATIoN on IowaSAFETY-GUARD FOR FACTORY-CHURNS.

To all whom t may concern.'

Be it known that I, `STEPHEN J. VAN KUREN, a citizen of the UnitedStates, residing at Cedar Rapids, in the county of Linn and State oit'Iowa, have invented certain new! and-useful Improvements in Safety-Guards `for Factory-Churns, of which the following is a specitication.

The object oit this invention is to provide a safety guard which isespeciallyy useful on factory churns as a protection vagainst accidentalinjury to workmen and others when the churn is in operation. i l

These churns comprise a revoluble drum of considerable size and providedwith doors adapted to be securely Jfastened in place by suitable deviceswhich project :from the drum and may engage the clothing of a workman orother person and result in injury to him,

It is the object of my invention to provide a guard rail of simple andinexpensive construction which will provide an effective guard againstaccidental contact of a person with the revolving drum. The inventionalso has for its Object to provide a guard which will permit access atall times to the drum for inspecting the contents and for putting insalt and other materials without necessitating any manipulation of theguard and which can be easily adjusted to permit acccess to the drum forremoving its contents and for cleansing and other purposes.

In the drawings I have shown one embodiment of the invention, inwhich--w Figure 1 is a side elevation illustrating the guard applied toone side of a combined churn and butterworker otl large size having twodoors;

Fig. 2 is an end elevation, partly in section;

Fig. 3 is a detail view of one section of the guard showing the railswungto upright position; j

Figs. 4 and 5 are detail sectional views of the saddle.

Referring to the drawings, 6 designates the churn, 7 theV end sup-portsand 8 the pipe girderswhich connect the supports and form therewith theframe iny which the drum and its operating mechanism vare supy ported.

Arms 9 are fastened at suitable intervals on the pipes 8 andare providedwith projecting end clamps 10 in which the posts Specification ofLetters Patent.

11 are `mounted. These posts project lupwardly in an angular directionto about the plane of the axis of the drum and as manyposts may beprovided as found necessary or desirable. Y In a large churn, such asillustrated in the drawings7 three posts are preferable and in a smallerchurn two` posts will be sufficient. In the construction illustrated inthe drawings, a sleeve 12 is pivotally mounted at 13 upon eachof theouter posts and a saddle 14; is-mounted onthe center post. The guardrail consists of two parts 15 which are adapted toslide in the sleeves12 and each of which extends from an outer post to the inner post. Astop 16 is arranged on each of ksaid rail parts7 intermediate of itsends,

to limit the outward sliding movement of said part 'and a stop 17 mayalso be provided at the outer end of each of said parts to limit theinward sliding movement of said part. The 'inner end of each of saidrail parts is provided with a` downward projection or lug 18 which isarranged to engage a recess 19 in the bottom o1 the saddle to retain therail parts in fixed position in the saddle and to provide a continuousrailing from end Vto end of the drum.

The guard rail permits access to the doors 20 of the drum in theposition illustrated in Fig. 1 to enable inspection of the contents `and'for putting material into the drum.

Y dents and injuries therefrom. For a small churn it will only benecessary to provide l two posts, onewith a pivot sleeve and the otherwith a saddle, as will be readily understood from the drawings yand theforegoing description. v

I am aware that changes in the form and proportion of parts and in thedetails o construction of my invention may be made without departingfrom'the spirit or sacrifcing any ofthe advantages of the invention andI would hav@ it understood that I y i ,desir'ekto niake allwsuchcnanges'as loe found'desirable to` adapt Ythe invention to 'so far aslthe sane shall VcomeWithin the scope" lof the appended olainis ain also'-ayyare''that the'invention may be employed l in co1ilginectionY Withlagreat vaietyof ohuins aii'd'foth'en dairy'-niachi'nery which it is' not'xnecessa'ry to specify'l imdetail,V and -I' desire Y.
